Hydroformylation Reaction of Alkylidenecyclopropane Derivatives: A New Pathway for the Formation of Acyclic Aldehydes Containing Quaternary Stereogenic Carbons

The rhodium-catalyzed hydroformylation reaction of methylene- and alkylidenecyclopropane derivatives proceeds under mild conditions to lead to the exclusive formation of linear aldehydes and the stereointegrity of the quaternary carbon center remains unaffected in the process.
